Team Rooter technician came out for sewer backup. Tech had to saw cut and jack hammer the asphalt and excavated approximately 3-4 feet deep. Tech replaced the damaged clay pipe and performed a pipe burst method and replaced about 90ft. We installed polyethylene pipes. Tech had to make a repair on the broken clay pipe. Tech wart-hogged the 6 inch clay pipe and eliminated all the roots and the debris in the lines. After line was prepped, we inverted a transition shot and sealed all breaks and cracks in the clay pipe. We ran a camera and inspected the rest of the sewer line. Work comes with 25 year warranty.
